DTF (Direct to Film) is the fastest-growing way to put full-color custom designs on apparel. This guide explains exactly how DTF printing works — from film to finished shirt — in plain English, with no jargon and no prior experience needed.

DTF (Direct to Film) is a heat-transfer printing method where your design is printed onto a sheet of clear film with color ink plus a white underbase, coated in hot-melt adhesive powder, cured, then heat-pressed onto a garment and peeled away. The result: a vivid, full-color print that bonds to almost any fabric, in any color.

DTF printing is a five-step process. Each step has a clear purpose, and once you see the whole flow, the file requirements (covered later) make a lot more sense.
A DTF printer lays your artwork onto a clear sheet of PET (polyester) film using special water-based pigment inks — first the full-color CMYK image, then a layer of white ink behind it. The film is printed in reverse so the design reads correctly once it is transferred.
While the ink is still wet, a fine hot-melt adhesive powder is dusted over the printed area. The powder only sticks to the wet ink, not the bare film. This powder is the glue that will eventually bond your design to the fabric.
The powdered film is heated — in a curing oven or under a heat press without contact — until the adhesive melts and gels onto the ink. After curing, you have a finished, shelf-stable transfer that can be pressed now or stored for later.
The cured film is placed face-down on the shirt and pressed with firm, even heat and pressure (commonly around 300–325°F for 10–20 seconds — always follow your film supplier specs). The heat reactivates the adhesive and bonds the design into the fabric.
After pressing, the clear PET film is peeled off — either hot or cold depending on the film type — leaving only your design fused to the garment. A quick second press through a cover sheet helps lock it in and improve wash durability.
The single most important thing that sets DTF apart is the white ink underbase. Printer inks are translucent — if you printed a red design straight onto a black shirt with no white behind it, the red would turn dark and muddy because the black fabric shows through.
DTF solves this by printing a layer of solid white ink behind your colors. That white layer blocks out the garment underneath and gives your colors a clean, opaque surface to sit on. This is exactly why DTF can print a bright, accurate design on a black, navy, or red shirt and have it look just as vivid as it would on white.
Here is the part beginners need to know: you do not create the white layer yourself. The printer's RIP software generates it automatically based on the non-transparent areas of your file. If a pixel is fully visible, it gets white ink behind it. If a pixel is transparent, it gets nothing.
That is why a clean transparent background matters so much on DTF. A leftover white background prints as a white rectangle, and soft, semi-transparent edges get partly filled with white ink — creating a faint "halo" or ghosting outline around your design. Getting transparency right is the difference between a crisp print and an amateur-looking one.
DTFWiz tip: Use the Make Print Ready scanner to catch white backgrounds and halo-causing edges before you print, or fix a ghosting outline directly with our white haze fix.
No printing method is perfect for everything. Here is a fair look at where DTF shines and where it has trade-offs, so you can decide if it fits your project.
When it is pressed correctly on quality film, a DTF transfer is genuinely durable — it stretches with the fabric and survives repeated washing without significant cracking or fading. The catch is that durability is earned, not automatic. Almost every story of a DTF print cracking or peeling comes down to one of three controllable mistakes:
To keep your transfers looking new, wash garments inside-out in cold water, skip harsh bleach, and avoid high-heat drying. A quick second press through a cover sheet after the first peel also helps lock the print in. Follow your film supplier's exact time and temperature specs — those numbers exist for a reason.
DTF is not always the right answer — it depends on your fabric, order size, and the look you want. Here is a fair, quick comparison to the three methods people ask about most.
DTG prints ink directly into the shirt, so it has almost no hand-feel and looks most natural on 100% cotton — but it struggles on polyester and dark synthetics and needs pretreatment. DTF prints onto film first, then transfers, so it works on nearly any fabric and color without pretreatment, at the cost of a slight film feel.

DTF works on cotton, blends, and dark garments of any color because it carries its own white underbase — something sublimation simply cannot do.

But it needs screens, setup, and separations per color. DTF wins for full-color art, photos, gradients, and small or one-off orders where screen setup is not worth it.

DTF stands for Direct to Film. Your design is printed onto a sheet of PET film (rather than directly onto the shirt), coated with hot-melt adhesive powder, cured, and then heat-pressed onto the garment. The film is peeled away, leaving the design bonded to the fabric.
Print your design onto clear film with color ink plus a white ink layer, dust hot-melt powder onto the wet ink, cure it with heat, press the film face-down onto the shirt, and peel the film off. The powder acts as glue that fuses your design into the fabric.
The white underbase is a layer of white ink printed behind your colors. Because fabric — especially dark fabric — would otherwise show through and dull your colors, the white layer gives the design something opaque to sit on. It is the reason DTF can print bright, accurate color on any garment color, and it is generated automatically from the transparent areas of your file. That is why a clean transparent background is so important.
A properly pressed DTF transfer on quality film holds up well to repeated washing without significant cracking or fading when cared for correctly. Durability depends on using good film and powder, fully curing the adhesive, and pressing at the right time, temperature, and pressure. Wash inside-out in cold water and avoid high-heat drying to extend its life. Under-curing or a weak press is the usual cause of early cracking or peeling.
DTF works on a very wide range — cotton, polyester, blends, and even tricky materials like nylon, canvas, and leather — in any color, light or dark. Because DTF carries its own white underbase, it does not need a light or polyester garment the way sublimation does, and it does not need pretreatment like DTG.
You need a print-ready PNG with a transparent background at roughly 300 DPI for your final size, in RGB color. The RIP software your printer uses generates the white underbase automatically from your transparency, so you do not add a white layer yourself. DTFWiz can scan any image for free and fix transparency, resolution, and edge issues before you print.
Yes. DTF has a gentle learning curve compared to screen printing — there are no screens to burn, no weeding like vinyl, and no pretreatment like DTG. You can order ready-to-press transfers (or gang sheets) and only need a heat press to apply them, which makes it one of the most beginner-friendly ways to start a custom apparel business.
